Random Black Screens

Hello, I am getting random black screens after logon. PC can go for over 3 hours fine, then a black screen. Another time it goes to a black screen right after a log on. It is random when it happens. The only way out of it is to do a reset.
I wanted to ask if anyone has experienced this before, and what to do to solve this issue.

Random black screen flickering issue

Win10 Enterprise version 1909 build 18363.720

So I've been trying to troubleshoot an incredibly annoying screen flickering issue for months now.

I have a dual monitor setup, one is an Asus ProArt PA248 connected via Display port, and the other is actually a 32inch Toshiba TV connected via HDMI.

This setup ran fine for years and then one day I started getting a random black screen flicker, some details about the issue:
- Both monitors flicker together, it isn't isolated to just 1 of them
- Happens every 5-10 seconds, randomly
- It can go for days without any issues, and kicks in randomly at random times
- There's no colors mixed into the flicker, it's pure black

Some troubleshooting steps I've tried
- New cables, no luck
- Messing with every driver I can find, stock windows drivers and all versions of Intel display drivers
- Someone suggested I bypass the built in Intel display adapter and MB ports & drivers so I bought a cheap GT 1030, was fine for a couple days then the exact same flicker issue started back up, so the issue doesn't even seem to be display/driver/graphic card related
- Booting into safe mode the issue went away, it could have just been a random coincidence but I found it interesting that the issue stopped while I was in safe mode

My PC hasn't changed much over the years so all the obvious troubleshooting hasn't led anywhere, I'm not sure where to look or what to try next, the PC is a little dated at 6 years but still runs fine otherwise I'd hate to have to build out a new system just because of this issue.

 

Random Black Screen

Re-installed Catalyst 8.35 drivers (from the original cd) - no luck. Still getting the random black screen.
